230 250 292 Chevy 6 valve cover CNC 3/4 thick billet spacer
230 250 292 Chevrolet Six cylinder, CNC machined, 3/4 thick Aluminum Valve cover spacer.
Unfortunately the Chevrolet Inline six stock and aftermarket valve covers are widest at the bottom right where don't need it to be. With the addition of high performance valve train components such as large diameter retainers, wide body full roller rocker arms, stud girdle, tall spring install height for big lift Cam Shafts.
Many of these upgrades have created a valve cover clearance challenge. One way we have found to navigate this clearance issue is to raise the valve cover up.
This spacer is computer designed, and CNC machined from a slab of billet 6061-T6 aluminum plate. It was selected to create a perfectly straight, SHOW QUALITY, ready to install spacer to be used under any brand valve cover, on any cast iron GM non-integrated head.
If you are using an original cast iron water outlet a front outlet spacer will be needed.
The photos show the aluminum slab prior to machining and a look at a spacer mockup for a complete and detailed visual.
The head and valve cover are not included with this spacer, They are only in the photo to show complete function.
The slab of 6061-T6 aluminum plate cost over $70.00
